Classic Superlight down bags capture the spirit of the west, of adventure and that no boundaries, unrestrained freedom we all moved here for. If you feel claustrophobic in the connes of a mummy bag, then welcome to the unfettered open space of a semi-rectangular bag made with super lightweight materials. These Big Agnes System bags use our full pad sleeve design. Features: - Integrated full pad sleeve. Never roll off your pad again - DownTek water repellent down insulation - warm, dry and environmental friendly - Rectangular shape offers more room in foot box and shoulders - Recycled mesh storage sack & nylon stuff sack included - Built in pillow pocket holds a fleece or Big Agnes pillow - 70" YKK #5 zipper. Mate together our left and right zip bags with same size zipper - No-draft collar seals around neck to keep cold air from sneaking in - No-draft wedge insulates the connection between the bag and pad - No-draft zipper tube insulates along the length of the zipper - Pertex? rip-stop nylon - Featherweight, high thread-count fabric that is soft as silk with a small packing volume. WR surface treatment to repel water - Lining: Nylon taffeta - Flow Construction: Insotect Flow is a flow-optimized insulation system that delivers uniform heat distribution and natural body contouring through its revolutionary baffle design. Flow Construction eliminates lateral and vertical down shifting by using vertical chambers with Flow Gates to regulate fill positioning and density. Strategically placed Flow Gates minimize vertical down shifting while vertical chambers minimize lateral shifting. With continuous vertical Flow chambers in place of traditional side seams, Flow bags eliminate potential cold spots which can occur with side seams. Vertical baffles now flow with your body for more rapid and uniform body heat distribution. - Left Zipper Specifications: - Pad Size: 20" x 78" - Color: Green/black - Fill Type: 800 fill DownTek - Fill Weight: 16.5oz - Bag Weight: 2lb 7oz - Shoulder Girth: 73" - Hip Girth: 69" - Foot Girth: 55" - Stuff Sack Size: M-8" x 17.5" - Compressed Bag Size: 8.5" x 8.5"
